Application September 19, 1931 Serial No. 563,805 -f 9 claims. (ci. 21e-3s) This invention relates to air temperature regulating apparatus for supplying air at an approximate desired temperature to the rooms of dwellings, offices, factorybuildings and other domestic or mercantile establishments. n

It is one of the objects of my invention in a preferred embodiment thereof to provide apparatus of this kind of a portable character, which may, for instance, be easily and quickly arranged in a window frame beneath a movable sash as a ventilator to change the temperature ,of the outside air before its admission to the room.

A more particular object of the invention is to provide such apparatus with easily adjusted means whereby it may be fitted within window frames of various widths, and the said means being of suchconstruction as to protect the frame against possible damage from direct contact of the casing of the apparatus therewith.

My invention in its preferred practical embodiment has as'its characteristic essential feature, a casing of suitable dimensions provided with openings in its opposite side walls for the inlet and outlet of air, and a temperature regulating means or unit supported in a central vertical plane from the top of the casing between-said inlet and outlet openings. Preferably, the supporting means for said unit is in the form of a hollow vertical partition of suitable conductive material spaced from the bottom of the casing and forming in conjunction with the walls thereof a circuitous air passage. The temperature regulating unit of comparatively small size is contained in the central lower portion of this partition, the side walls of which are suitably attached at their upper ends to the casing walls. A removable sealing means is provided for the upper open end ofthe partition. Thus the remaining space within this hollow partition provides a collecting chamber for the vapor or other temperature regulating medium. The small unit may be very economically operated while owing to they construction and relative arrangement of T its several parts, as will be hereinafter more fully described and illustrated in the accompanying drawing and subsequently incorporated in the subjoined claims.

In the drawing wherein I have illustrated one simple and practical` embodiment of the invention, and in which similar reference characters designate corresponding `parts throughout the several views,-

` Figure 1 is a front elevation of my improved air temperature regulating apparatus, a portion of the casing being broken away, and disclosing the temperature regulating unit;

Fig. 2 is a transverse sectional view taken substantially upon the yline 2-2 of Fig. 1; and

Fig. 3 is a horizontal sectional view taken substantially upon the line 3 3 of Fig. 1.

Referring in detail to the drawing, the casing is preferably of elongated rectangular form and includes the front and rear walls l and 2 respectively, top and bottom walls 3 and 4 and opposite end walls 5 and 6 respectively. The topwall 3 of this casing is preferably in the form of a movable cover which may be hingedly or detachably connected to the casing, and in the present instance asr indicated in Fig. 2 of the drawing, has a slidable connection with flanges suitably formed on i the upper ends of the iront and rear walls l` and 2 of the casing. The underside of this cover 3 Vis provided with-a sheet of sealing or insulating material indicated at 3. for a purpose which will be presently disclosed.

The bottom wall v4 of the casing is,.in the illustrated construction, disposed at a transverse inclination downwardly from thefront wall 1 to the rear wall 2 of the casing, so that it will properly seat upon a window sill. 'y T At the opposite ends of the front wall 1 of the casing, the longitudinally adjustable plates `7 and 8 are suitably connected therewith and are adapted for engagement with the opposite vertical portions of a window frame to retain the casing in removablyv xed relation thereto. These plates lmay be provided with suitable finger-pieces 9 for the convenient operationthereof, and `adjustable meansl of any preferred type such as that indicated at l0 is also prcvided'to cooperate with tongues 10 on the lower vends of ksaid plates to retain the latter in their adjusted positions.,

The front and rear walls 1 and 2 are provided with suitably formed outlet and inlet openings 11 and 12 respectively, and the various walls of the casing are preferably internally covered with a suitable insulating and reproof material such as asbestos or the like, as indicated by the characters 1 to 6 respectively.

In the present instance, for the purpose of heating the incoming air, I have shown a heating unit 13 which may consist of any suitable device adaptable for use in the present apparatus. As shown, this unit may consist of the asbestos plate 14 constituting a core upon which the heating resistance wires 15 are suitably Wound. These wires or conductors are connected with suitable leads 16 which in turn are connected with the contacts of a suitable socket 17 mounted in one side wall of the casing and adapted to receive the prongs of a conventional connecting plug (not shown).

The heating conductors or resistance wires are preferably covered with sheets or layers of mica composition material 18, and this unit is supported or mounted within the housing 19 preferably of sheet aluminum or other good conductive material. As herein shown, this housing constitutes a central hollow partition extending substantially the full length oi the casing and having a closed lower end spaced from the bottom wall of the casing. The parallel vertical walls of this housing or partition preferably have their upper edges divergently extended towards the front and rear side walls of the casing, and suitably attached to the upper edges thereof. Between these attached edges, the upper longitudinal opening of this hollow partition is securely sealed by the insulating sheet 3 on the cover` 3 of the casing, as clearly shown in Fig. 2 of the drawing. Thus, it will be apparent that this housing or hollow partition in conjunction with the casing walls forms a circuitous air passage through the casing between the inlet openings 12 and the outlet openings 11 in the upper end portions of the opposite side walls of the casing.

The heating or other temperature regulating unit 13, as clearly seen in Figs. 1 and 2 of the drawing, is of comparatively small size with respect to the area of the partition or housing, and is located within the lower central portion of the latter. Thus, it will be evident that since this relatively small unit will consume little current, a desirable economy in operation is eiiected. Nevertheless, as the generated heat or other temperature regulating vapor will collect and fill the interior of the housing, each of the walls 19 of comparatively large area, will throughout their extent, act to conduct and radiate the temperature regulating medium more or less uniformly throughout al1 portions of the air passage through the casing.

It is, of course, to be clearly understood that the specic form of the casing, and of the supporting housing or partition for the temperature regulating unit is merely suggestive, and may he varied at will, depending upon the particular use or application of the apparatus. It will further be evident that the air passing through the casing may be cooled instead of heated by the use of an air cooling means such as solidified carbon dioxide in place of the heating unit above referred to. In such event, it is apparent that the openings 11 and 12 in the casing walls may be otherwise arranged.

From the above description considered in connection with the accompanying drawing, the operation and several advantages of my improved air temperature regulating apparatus will be readily understood. As the air enters the casing through the openings 12, it immediately comes into contact with the adjacent wall 19 of the central partition and is thereby directed downwardly around the lower end of said wall and then upwardly in contact with the opposite side wall of the partition, so that such air will be continuously iniiuenced by the air temperature regulating medium and will pass from the casing through the openings ll at approximately the desired temperature. In the illustrated use of the invention for the purpose of heating the air, the upward flow of highly heated air to the openings 11 will tend to cause a continuous circulation of the air through the casing in accordance with the well known principle of an inverted siphon. It will be understood that the air in the inlet passage, above the heating unit 13, is relatively cocl, but progressively increases in temperature as it moves downwardly in Contact with the lower end portion of the partition 19, which is directly heated by the unit 13. Below said wall a sudden expansion of the heated air takes place, producing an induction eiect on the inlet side of the passage and an upward pressure on the outlet side thereof, where the air is further heated and its discharge through the outlet openings facilitated. Therefore, rapid flow of the air will be produced and Warm fresh air discharged through the openings l1 into the room.

While I have herein shown a simple and practical embodiment of my improved air temperature regulating apparatus, it will he evident from the foregoing 'that the essential features thereof may also ce exemplr d in various other alternative structural forms. Accordingly, the privilege is reserved of resorting to all such legitimate changes therein as may be fairly embodied within ihe spirit and scope oi the invention as claimed.
